Image loading complete


I have loaded a jpeg image in flash. Now I need the handler after the loading complete

I have used the following code.

    var imageLoader:Loader = new Loader();
    var req:URLRequest=new URLRequest(arr[0]);
    imageLoader.addEventListener(Event.COMPLETE, image_func);
    function image_func(e:Event):void {
        trace("image laoded complete");

The above code is not working for loading complete.

can any one point me where I am going wrong?

thanks in advance.
